Act I. The miller, _Tio Lucas_, is living a happy life with his

beautiful wife, _Frasquita_. Her love is so true that jealousy, to which he is inclined, cannot thrive. Jealous? Yes, he has a bump of jealousy. True, the _Corregidor_, who eagerly concerns him about the miller's pretty wife, has one too. But no matter, he is a high, very influential functionary. Meanwhile _Frasquita_ loves her _Tio Lucas_ so truly that she can even allow herself a dance with the _Corregidor_. Perhaps she will cure him so, perhaps she will obtain in addition the wished-for official place for her nephew. The _Corregidor_ too does not keep her waiting long and _Frasquita_ makes him so much in love with her that he becomes very impetuous. Thereupon he loses his balance and the worthy official falls in the dust, out of which the miller, without suspecting anything, raises him up. But the _Corregidor_ swears revenge.
